没问题。

When to use

This is a highly versatile phrase used to agree to a request or to accept an apology. It reassures the listener that a task is manageable or a mistake is forgiven.

Word breakdown

The phrase uses the negator 没 (méi), which specifically negates possession or existence. It is essentially a shortened form of 没有问题 (méi yǒu wèn tí).

• 没 (méi): not have (negator for possession)
• 问题 (wèn tí): problem / question

Choosing the right negator

In Chinese, you cannot use 不 (bù) to say 'no problem'. The negator 没 (méi) is strictly used to indicate the absence or lack of something, acting as the negative form of 'to have'.

Notes

A standard, reassuring response to requests or apologies, literally meaning 'not have problem'.
